What we know now: pouch surgery 40 years on

For many patients, ileal pouch-anal anastomosis (also called ileo-anal pouch surgery) not only eradicates disease but also preserves the anal sphincter, enabling the patient to defecate in the normal way. Pouch surgery is approaching 40 years and within this time has become the 'gold standard' in surgical management for ulcerative colitis and familial adeomatous polyposis. Much of the research over the years has explored surgical techniques and pouch function, failure and satisfaction, as well as long-term follow-up; however, some pouch problems continue to be a mystery. This short article aims to bring us up to date with what we know now that might have been beneficial to know then.
